SPECIFICATION forming part of Letters Patent No. 420,729, dated February4, 1890.

Application filedNovember 20, 1888. Serial No. 291,408. (No modeL)Patented in France May 16, 1888, No. 190,622 3 in Belgium May 17, 1888,No. 81,874, and in Germany May 27,1888.

i To aZZ whom it may concern.-

Be it known that I, PAUL MONCHARMONT, engineer, of Paris, in theRepublic of France, have invented a Machine for Notching Keys or Wedges,(for which I have obtained Letters Patent in France, dated May 16, 1888,No. 190,622; in Belgium, dated May 17, 1888, No. 81,874, and in Germany,dated May 27, 1888,) of which the following is a specification.

This invention relates to a machine more particularly intended fornotching or channeling the beveled keys employed in railway chairs orsupports of the class described in an application for Letters Patentfiled by me March 16, 1888, Serial No. 267,441; but it is alsoapplicable to the notching or channeling of other keys or Wedges forrailways and tramways or other like purposes.

The most important characteristics of this machine relate to theconstruction and operation of the punch or cutting-tool and to the meansemployed for holding the key or wedge in position while it is beingacted upon by the tool and for securing the machine itself in positionbyconnecting it to the permanentway or other fixed support, and to thegeneral combination of the parts, as hereinafter described.

In the accompanying drawings, Figure 1 Fig. 11 represents the tackle,partly in sec-' tion, along the line 11 12, Fig. 12, and thepunching-machine A being represented in elevation. Fig. 12 representsthe apparatus in plan. Fig. 13 represents a transverse section on theline 13 14, Fig. 12. Figs. 14 and 15 represent the keys. Fig. 16 is across-sectional view of a key.

The machine illustrated in the drawings is arranged for cutting notchesor channels in keys of the prismatic form represented in hereinafterdescribed.

Figs. 14, 15, and 16. The side to be notched (00 y, Fig. 16) is beveledrelatively to the lower surface. It is necessary to form the notchperpendicular to this lower surface and at a constant depth or distancefrom the edge. The distance of the notch from the end may vary, asindicated by the dotted lines in Figs. 14 and 15. The side to be notchedand the opposite side may not be parallel; but the key may taper to oneend, either as shown by Fig. 14 or by Fig. 15.

This machine is constructed with a standard or frame A, the base ofwhich is formed with an angular transverse opening for the reception ofthe key a to be notched or channeled and of a distance piece or block1?. Above and at right angles to this opening there is a cylindricalhole or socket, in which works a tool-holder c, carrying a punch O,secured by a set-screw o, the head of which works in a suitable slot f,Fig. 5. The lower part of the base is provided with a circular die-piececl, formed with an elliptical or elongated central opening and fittedinto a recess in the base, being retained in position by two parallelpins or keys driven in horizontally through the base and engaging withthe sides of the die-piece. A cleaning-hole g is provided underneath thedie-piece.

Lugs 13 B are provided at the sides of the bed, being perforated withcylindrical holes, which are utilized for fixing the machine, as Theunder side of the base is provided with legs 19, to which a soleplate 0of suitable shape and dimensions is attached by screws. The upper partof the frame is constructed with mechanism such as that illustrated inthe drawings or of any other suitable construction for obtaining therequisite power for working the tool or punch O, employed for notchingthe key a.

The tool-holder c is made with a cylindrical shank, and at its lowerextremity presents an inclined plane perpendicular to or bisecting theprolongation of the long axis of the elliptical opening in thedie-pieced, the said plane terminating in horizontal planescorresponding to the thickness of the sides of the socket of theto0l-holder.

The punch or tool 0 is made of elliptical or other suitable form intransverse section, be-

ing rounded or semicircular at the ends in the example illustrated, andis retained in position in the socket of the tool-holder c, which is ofa form fitted to receive the shank of the tool. This tool is proyidedwith an extension 0 on the back or side opposite to that on which thecutting-edge O is situated, which extends into the hole in the die-pieceand forms a guide and support for the punch or cutting-edge 0 A hole t,closed byascrewed plug, is formed in the sole-plate C under the hole inthe die-piece to enable the punch or tool to be removed. Thecutting-edge O is semicircular, as indicated in the drawings, or ofangular or any other suitable form corresponding to that of the notch orchannel to be out in the key 0.. According as the key is intended to bedriven in from left to right, as in Fig. 21, or from right to left, Fig.22, it is supported in the machine by a filling piece or block b, Figs.9 and 10 or 7 and 8, in which the key is indicated in dotted lines. Eachof these filling-blocks represents a rectangular parallelopipedonbisected longitudinally by a vertical plane, forming with the side ofthe parallelopipedon an angle equal to that formed by the intersectionof the horizontal lines in the surfaces between which the key is to bedriven. The blocks b are provided with a projection b, Fig. 10, hearingagainst the thick ends of the keys and forming a stop, which preventslongitudinal displacement of the keys during the punching, and with ahandle Z) to facilitate the manipulation. By means of these blocks, anynumber of which may be provided with the machine corresponding to thedifferent sizes of keys, the notching or channeling is enabled to beperformed with perfect regularity at the same position and depth, thekey being retained longitudinally in position during the operation bythe heel or projection 11 and laterally by the side face of the block.The punch makes a perfectly-clean out Without burrs, as the work and thetool are effectually prevented from yielding or moving laterally, theformer being supported by the block b and the latter being supported bythe holder 0 and by the extension 0. This arrangement of the tool 0 isof great importance, constituting a cutting-punch perfectly certain andregular in its action.

This notching or channeling machine may be screwed or otherwise securedto a table or bench by means of the sole-plate (I. This plate may bedispensed with by making the base with feet adapted to lix it inposition; but as the machine is especially intended to be used fornotching the beveled metal keys employed in the construction of railwaysit is more convenient to provide means for fixing it to one of the railsof the permanent way, as hereinafter described. These means ofattachment or holding-tackle are illustrated in Figs. 11, 12, and 13 ofthe accompa' nying drawings.

The tackle represented in Figs. 11, 12, and

13 is composed of two U-shaped bars or forks E and F, connected byastraight barT. The fork E is provided with two hooks or claws E E,shaped to embrace and fit the rail R, as indicated in Fig. l1,the railbeingjammed in the hooks by means of wooden wedges G, connected to theapparatus by chains. This fork E is jointed to the straight bar T by apin h, passed through an eye formed in the bar and through lugs on thefork and secured by a nut. The bar T is connected at the other extremityto the fork E by a pivot i, Fig. 12, formed on the end of the bar andfitting in a hole or socket in the fork. The legs of the latterterminate in pins fitting into the cylindrical holes in the lugs 13 B,Fig. 1, hereinbefore referred to, being secured to the punching-machineby pins j, attached to the base of the machine by short chains. Thedouble joint formed by the pin it and pivot 2' enable the machine toadjust itself readily to any irregularities or inequalities in the levelor incline of the ballast of the road-bed relatively to the rail R. I Itis evident that in practice the machine may be steadied and retained inposition by attaching it to any other stationary support, the rail Rbeing merely illustrated by way of example as being the most convenientsupport in working on the permanent way.

I claim as my invention- 1. A machine for notching railway-chair andother like keys or wedges, comprising a standard frame having a lateralopening for the keys, in combination with a key-l1older,a notching-tool,and a die-piece, substantially as described.

2. A machine for notching railway-chair and other like keys or wedges,comprising a frame A, having a transverse opening for the key and itsholder, a vertical opening for the punch and tool-holder, aclearing-hole, and perforated lugsB to secure the machine, substantiallyas described.

3. In combination with a machine for notching railway and other likekeys or wedges, a key-holder consisting of a rectangular block againstone side of which the key abuts and provided with a handle, andprojection 11 to prevent longitudinal displacement of the key,substantially as described.

at. In combination with a punching-machine, tackle for fixing saidmachine in position, consisting of two forks, a bar connecting theforks, adjusting devices, hooks to grasp the rail and wedges, and meansto fasten the tackle to the pnnching-machin e, substantially as hereindescribed.
